WILLIAM A. FEN'TON, 0F SIOUX CITY, IOWA.

GAS-PRESSURE REGULATOR.

Application filed September l, 1909.

Specification of Letters Patent.

Patented June 28, 1910.

Serial No. 515,697.

To all whom it may concern:

Be it known that I, WILLIAM A. FENTON, a citizen of the United States, residing at Sioux City, in the county of Woodbury and State of Iowa, have invented new and useful Im rovements in Gas-Pressure Regulators, 0 which the following is a specification.

My invention relates to the meet acetylene as an illuminant and the object of the invention is to improve upon and make more useful the lamp invented by me and patented on the 27th day of July, 1909, No. 929,296, as well as to generally render the use of acetylene as an illuminant more agreeable and satisfactory.

The invention has relation especially to the regulation of the pressure and supply of gas for illumination and is in such respect an improvement upon my previous invention.

In the accompanying drawing the figure is a cross-section of my invention.

It is well known that in the generation of gas the gas pressure is variable and that the light is uncertain for this reason.

The object of my invention is to render the pressure even and uniform and to be able to control the pressure of the gas as desired. That object is attained by the-use of the device now described.

My invention may be used by adjustment within the lamp or gas generator or connected therewith by means of pipes conveying the gas to the regulator.

Attached to the lower end of the jointed pipe 6 by a coupling g is a can J having an upper. and smaller extension or gas :holder K, which 0 ns into the pipe e. The

latter is provide with the usual cock, a section of which, f, is shown, and the usual tip. e. The can and extension are separated by the diaphragm L forming the bottom of the holder K. In the middle of the diaphra is secured, by means of the nuts F and a stem M, tapering at the lower end and inclosed by a casing N, forming a taper valve. The port of the casin is smaller below the stem and is ada te to be connected with the reservoir 0 the lamp or so arranged that the gas is conducted from the reservoir to the port. From the two sides of the casing pipes 0 lead at right angles to the stem to the sides of the can J where they bend upward and open into the gas holder K at the outside of and above the diaphragm through the chambers h. The casing N is threaded externally and supports a packing nut H at the upper end and an internally threaded adjustment nut P near the lower end. Between the nut and the diaphragm rests a coil spring R, encir cling the stem and the casing. The external part or lower end T of the casing is also threaded and a pipe leading from the gas reservoir of the lamp may be attached, if the regulator is adjusted and used on the outside of the lamp.

The supply or outlet of gas to the burning jet is controlled by the taper valve and the valve is regulated by the action of the diaphragm and the tension of the spring. If the supply of gas is too great the pres sure on the diaphragm of the gas in the chamber K causes the stem to cut ofi the gas from the lamp or generator, and if the supply is not sufiicient the diaphragm is released from the pressure and the spring forces up the stem and opens the port. The tension of the spring is regulated by the adjustment nut. The can J is intended to exclude the gas except from the lower en-' trance to the port of the casing, and to protect the bottom of the diaphragm from pressure of the gas from the lamp or generator.

Having described my invention, what I claim as new and desire to secure by Letters Patent, is

In a gas pressure regulator, the combination of a can J having an extension or gas holder K communicating with the outlet of gas su ply, a diaphragm forming the bottom 0 the gas holder and operated by the pressure of gas therein, the diaphragm separating the can from, the extension, a stem tapering at the lower end secured to the diaphra a threaded casing for the stem opening outwardly from the can, pipes, leading from the port of the casing to the holder K, an adjusting nut on the casing and a coil spring encircling the stem and easing between the diaphragm and the adjusting nut, substantially as described.

In testimony whereof I have hereunto aflixed my name in the presence of two sub-v scribing witnesses.

WILLIAM A. FENTON.
